[0028] For the convenience of description, some nouns or terms involved in the embodiments of the present application are explained below:
[0029] Oxygen production module: refers to the equipment that uses air compressor and molecular sieve to separate oxygen and nitrogen in the air to obtain air with high oxygen concentration.
[0030] As introduced in the background technology, the air compressor in the oxygen production module in the prior art generates relatively loud noise when working, and the molecular sieve and filter in the oxygen production module are inconvenient to replace because they are designed to be outdoors. To solve the above problems, the embodiments of the present application provide an oxygen production air conditioner, a control method for an oxygen production air conditioner, and an oxygen production air conditioning system.
[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0032] The present application provides an oxygen-generating air conditioner, such as Figure 1 and Figure 2 As shown, including:
[0033] An air conditioner outdoor unit 10, the air conditioner outdoor unit at least comprises an air compressor 11, and the air conditioner outdoor unit is located outdoors;
[0034] The air conditioner indoor unit 12 at least comprises a molecular sieve 13 and a filter 14. The air conditioner indoor unit is located indoors. The air compressor and the molecular sieve are connected by a pipeline. The filter is located between the air compressor and the molecular sieve.
[0035] Through this embodiment, the air compressor is designed on the outdoor unit of the air conditioner, the molecular sieve and the filter are designed on the indoor unit, the air compressor and the molecular sieve are connected by a pipe, and the filter is designed between the air compressor and the molecular sieve. The outdoor installation of the air compressor effectively reduces the indoor noise and provides a quieter use environment. The molecular sieve and the filter are installed indoors, and users can easily replace and maintain them, reducing maintenance costs and difficulties. The above solution solves the problem of inconvenience in replacing consumables such as molecular sieves and filters outdoors, and also solves the problem of noise affecting the indoor environment when the entire oxygen production module is placed indoors for operation.
[0036] Specifically, the air compressor in the oxygen production module in the existing solution will generate a lot of noise when working. In order to reduce the impact on the indoor environment, the oxygen production module is usually designed to be installed outdoors. The molecular sieve and filter in the oxygen production module are consumables and need to be replaced regularly. Since these components are designed to be outdoors, it is inconvenient to replace them, which increases the maintenance cost and difficulty for users.
[0037] Specifically, the above scheme of the present application effectively solves the problem of noise affecting the indoor environment when the entire oxygen production module is placed indoors for operation and the problem of inconvenience in replacing consumables such as molecular sieves and filters outdoors. The filter can effectively remove dust, particulate matter and other impurities in the air, ensuring that the air delivered to the molecular sieve is clean, thereby improving the service life and separation efficiency of the molecular sieve.
[0038] The outdoor installation of the air compressor effectively reduces indoor noise and provides a quieter use environment. The molecular sieve and filter are installed indoors, so users can easily replace and maintain them, reducing maintenance costs and difficulty.
[0039] Specifically, the solution of the present application effectively solves the problems of noise, inconvenient maintenance and complex equipment of the traditional oxygen production module by designing the air compressor, molecular sieve and filter screen outdoors and indoors respectively, and utilizing natural cooling.
[0040] Specifically, Figure 1 As shown, a cavity 15 for installing an air compressor is designed on the outer housing, and the air compressor is installed on the outer housing. A molecular sieve is designed on the indoor unit. A pipeline is designed to connect the outdoor air compressor and the indoor molecular sieve, and a filter is designed indoors on the pipeline path.
[0041] Specifically, an air compressor pressurizes outdoor air and transports it to the molecular sieve through a pipe. During the transportation process, the air passes through a filter to remove impurities. The molecular sieve separates the oxygen and nitrogen in the air.
[0042] An air compressor is a device used to compress air. It reduces the volume of air by increasing its pressure. In an oxygen-generating air conditioning system, the role of the air compressor is to compress outdoor atmospheric pressure air to a higher pressure for the subsequent oxygen separation process. The process of compressing air generates a lot of heat, which is why the temperature of the air compressor rises when it is working. The noise and heat dissipation of the air compressor are usually taken into consideration during design to ensure its efficient and stable operation.
[0043] Molecular sieve is a material that has the function of adsorbing and separating gas mixtures. Its structure contains many tiny holes, the size of which can be precisely controlled, so that it can selectively adsorb certain gas molecules in the air, such as nitrogen. In oxygen-generating air conditioning systems, molecular sieves enrich oxygen by adsorbing nitrogen from the air. Molecular sieves usually need to be regenerated regularly to restore their adsorption capacity, and the regeneration process usually involves heating and decompression.
[0044] The filter is used to remove impurities in the air, such as dust, pollen, smoke particles, etc., in order to provide clean air to the molecular sieve system. In oxygen air conditioners, the filter is located before the air enters the molecular sieve, which can effectively prevent impurities from entering the molecular sieve and affecting its separation efficiency and service life. The filter needs to be cleaned or replaced regularly to maintain its filtering effect.
[0045] In the specific implementation process, Figure 2 As shown, the molecular sieve comprises an oxygen outlet 16, which is used to distribute oxygen into the room.
[0046] In this solution, the oxygen outlet of the molecular sieve is connected to the indoor unit, and the oxygen is evenly distributed in the indoor space through the indoor unit, solving the problem of uneven distribution of indoor oxygen concentration caused by oxygen gathering in a certain place.
[0047] Specifically, the oxygen separated by the molecular sieve in the above-mentioned solution of the present application is connected to the indoor unit through the oxygen exhaust port, and the oxygen is evenly blown into the room through the fan of the indoor unit to improve the indoor air quality.
[0048] Specifically, the air compressor is a key component in the air conditioning system, responsible for providing pressure to the air and transporting it to the molecular sieve. However, the air compressor will generate a lot of noise during operation. Designing the air compressor on the air conditioner outdoor unit can effectively reduce the impact of the noise generated by the air compressor on the indoor environment. Molecular sieve is a highly efficient gas separation material that can separate oxygen and nitrogen in the air. The molecular sieve is designed on the indoor unit and connected to the indoor unit through the oxygen exhaust port. The fan of the indoor unit blows the oxygen evenly into the room, improving the indoor air quality and providing a fresher and healthier air environment. The filter is designed between the air compressor and the molecular sieve: the filter can effectively remove dust, particulate matter and other impurities in the air, ensure that the air transported to the molecular sieve is clean, and improve the service life and separation efficiency of the molecular sieve.
[0049] Specifically, Figure 2 As shown, the separated oxygen is delivered to the indoor unit through the oxygen exhaust port, and then evenly distributed to the indoor space through the fan 17 of the indoor unit to provide fresh air.
[0050] In the existing solution, the gas coming out of the air compressor is at a high temperature and needs to be cooled before passing through the molecular sieve. The traditional solution is to add additional cooling equipment, which not only increases the complexity and volume of the equipment, but also increases the cost.
[0051] In some embodiments, Figure 3 As shown, the molecular sieve includes a nitrogen outlet and an air inlet, the nitrogen outlet is connected to the air compressor through a first pipe 18, and the nitrogen discharged through the nitrogen outlet cools the air compressor; the air inlet is connected to the air compressor through a second pipe 19, the second pipe is located in the first pipe, the air compressor conveys air to the molecular sieve through the second pipe, and the air conveyed by the air compressor is cooled in the first pipe.
[0052] In this scheme, the molecular sieve separates oxygen and nitrogen in the air during operation. Oxygen is transported to the room through the oxygen outlet of the molecular sieve, while nitrogen is discharged through the nitrogen outlet of the molecular sieve. The first pipeline is connected to a part of the air compressor (usually the cavity or heat dissipation area of the air compressor). In this way, after the molecular sieve separates nitrogen, the nitrogen will flow back to the air compressor through the first pipeline, and the cooling effect of nitrogen will be used to help the air compressor dissipate heat and reduce its operating temperature. After the air compressor compresses the air, it needs to be transported to the molecular sieve for gas separation. In order to take advantage of the cooling effect of nitrogen reflux, an ingenious pipeline layout is designed. The air compressor transports air to the molecular sieve through the "second pipeline", and the second pipeline is designed inside the first pipeline. This means that the air with a higher temperature compressed by the air compressor will be heat-exchanged with the nitrogen in the first pipeline through the second pipeline during the process of transporting it to the molecular sieve. Nitrogen, as a cooling medium, can reduce the temperature of the air output from the air compressor, which not only reduces the need for additional cooling equipment, but also improves the separation efficiency of the molecular sieve.
[0053] Specifically, Figure 3 As shown, the first pipeline is the pipeline for the air compressor to transport air, and the second pipeline is the pipeline for exhausting nitrogen. Figure 3 The pink arrows in the middle indicate the air flow direction 20 , and the blue arrows indicate the nitrogen flow direction 21 .
[0054] Specifically, the nitrogen outlet of the molecular sieve is extended through a pipe to the air compressor cavity installed outdoors, and the air compressor is cooled by nitrogen. The pipe for the air compressor to transport air to the molecular sieve is designed inside the nitrogen exhaust pipe, so that the air output by the air compressor undergoes heat exchange in the nitrogen exhaust pipe, effectively reducing the temperature of the air output by the air compressor. This solves the problem of the need for additional cooling equipment for the exhaust gas from the air compressor. It also solves the problem of the air compressor being too hot and difficult to cool down during operation. The above solution solves the problem of the air compressor generating heat during operation, which causes the air compressor temperature to be too high, affecting work efficiency and service life.
[0055] Specifically, in the above scheme of the present application, the natural heat exchange and cooling design of the pipeline is used so that the oxygen production module does not need additional cooling equipment, which simplifies the equipment structure and reduces the volume and cost. The separated nitrogen is extended to the air compressor cavity installed outdoors through a pipeline, and the air compressor is cooled by nitrogen. The operating temperature of the air compressor can be effectively reduced, and its working efficiency and life can be improved. Through the above improvements, the oxygen-generating air conditioner not only improves the user experience, but also enhances the market competitiveness of the product.
[0056] Specifically, the nitrogen separated by the molecular sieve in the above solution of the present application is discharged to the outdoor air compressor through a pipeline, and the nitrogen can be used to cool the air compressor and reduce the working temperature of the air compressor. It can effectively reduce the temperature of the air compressor and improve the working efficiency and life of the air compressor.
[0057] Specifically, the above solution of the present application solves the problem that the exhaust gas of the air compressor needs additional cooling equipment. The natural heat exchange cooling design of the pipeline makes it unnecessary to add additional cooling equipment to the oxygen production module, simplifies the equipment structure, and reduces the volume and cost.
[0058] Specifically, the separated nitrogen is extended through a pipeline to the air compressor cavity installed outdoors, and the air compressor is cooled by nitrogen. This can effectively reduce the operating temperature of the air compressor and improve its working efficiency and life. The pipeline for the air compressor to transport air to the molecular sieve is designed inside the nitrogen exhaust pipeline, so that the air output by the air compressor undergoes heat exchange in the nitrogen exhaust pipeline. This can effectively reduce the temperature of the air output by the air compressor, and the natural heat exchange and cooling design of the pipeline makes it unnecessary for the oxygen production module to have additional cooling equipment, which simplifies the equipment structure and reduces the volume and cost.
[0059] In the specific implementation process, Figure 1 and Figure 2 As shown, the oxygen-generating air conditioner further includes a pressure sensor 22, a pressure difference sensor 23, a flow sensor (not shown in the figure), a first flow valve (not shown in the figure), a second flow valve 24 and an oxygen concentration sensor, wherein the pressure sensor is used to detect the pressure of the output air of the air compressor; the pressure difference sensor is used to detect the pressure difference on both sides of the filter; the flow sensor is used to detect the output flow of the output end of the air compressor; the first flow valve is used to control the output flow of the output end of the air compressor; the second flow valve is used to control the output flow of the output end of the molecular sieve; and the oxygen concentration sensor is used to detect the concentration of oxygen at the output end of the molecular sieve.
[0060] In this scheme, the pressure sensor is installed at the output end of the air compressor to monitor the pressure of the air output by the air compressor in real time. The differential pressure sensor is used to detect the pressure difference on both sides of the filter, that is, the pressure difference before the filter (clean air side) and after the filter (air filtered side). The flow sensor is used to detect the air flow at the output end of the air compressor to ensure that the molecular sieve is supplied with stable and sufficient air for gas separation. The first flow valve is connected to the output end of the air compressor to control the air flow output from the air compressor to the molecular sieve to ensure that the molecular sieve can obtain an appropriate amount of air for separation while avoiding unnecessary energy loss of the air compressor. The second flow valve is located at the oxygen output end of the molecular sieve to control the separated oxygen flow, adjust the oxygen supply according to the actual indoor demand, and ensure that the indoor oxygen concentration is maintained at an ideal level. The oxygen concentration sensor is installed at the output end of the molecular sieve to monitor the concentration of the separated oxygen. Through the precise monitoring and control of these sensors and valves, the air conditioning control can achieve automatic adjustment to ensure that air compression, filtration and oxygen separation are in the optimal state during the entire operation process, thereby providing a stable, efficient and safe oxygen supply while reducing maintenance costs and improving user comfort.
[0061] Specifically, an oxygen sensor may also be arranged at the position of the second flow valve.
[0062] In summary, the above solution of the present application effectively solves the problems of noise, inconvenient maintenance and complex equipment of the traditional oxygen production module by designing the air compressor, molecular sieve and filter screen outdoors and indoors respectively, and using natural cooling. This innovative design improves the performance and user experience of the oxygen production air conditioner.
[0063] In summary, in oxygen-generating air-conditioning technology, in order to improve indoor air quality, the air conditioner increases the oxygen content of indoor air by setting up an oxygen-generating module. The oxygen-generating module usually uses a combination of an air compressor, a molecular sieve, and a filter to produce oxygen. Since the air compressor makes a lot of noise when working, the oxygen-generating module is generally designed to be installed outdoors. However, the molecular sieve and the filter in the oxygen-generating module are consumables. If they are installed outdoors, it is quite inconvenient to operate when they need to be replaced. In addition, the temperature of the gas coming out of the air compressor is generally high and needs to be cooled before it can pass through the molecular sieve. The additional addition of cooling equipment causes the oxygen-generating module to become complicated, bloated, and large in size, occupying space. The present application provides a solution in which the air compressor is designed outdoors and the molecular sieve and the filter are designed indoors, while increasing the distance between the air compressor and the molecular sieve, so that the gas coming out of the molecular sieve can be naturally cooled down by the distance, without the need for additional cooling equipment, which facilitates the replacement of consumables while simplifying and miniaturizing the oxygen-generating equipment, thereby improving product competitiveness.
[0064] The method embodiments provided in the embodiments of the present application can be executed in a mobile terminal, a computer terminal or a similar computing device. Taking running on a mobile terminal as an example, Figure 4 FIG. 1 is a hardware structure block diagram of a mobile terminal of a control method for an oxygen-generating air conditioner according to an embodiment of the present invention. Figure 4 As shown, the mobile terminal may include one or more ( Figure 4 Only one is shown in the figure) a processor 102 (the processor 102 may include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA) and a memory 104 for storing data, wherein the mobile terminal may also include a transmission device 106 and an input / output device 108 for communication functions. It can be understood by those skilled in the art that Figure 4 The structure shown is only for illustration and does not limit the structure of the mobile terminal. Figure 4 More or fewer components as shown, or with Figure 4 Different configurations are shown.
[0065] The memory 104 can be used to store computer programs, for example, software programs and modules of application software, such as the computer program corresponding to the display method of device information in the embodiment of the present invention. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, that is, the above method is implemented. The memory 104 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some examples, the memory 104 may further include a memory remotely arranged relative to the processor 102, and these remote memories can be connected to the mobile terminal via a network. Examples of the above-mentioned network include but are not limited to the Internet, an intranet, a local area network, a mobile communication network, and a combination thereof. The transmission device 106 is used to receive or send data via a network. The above-mentioned specific examples of the network may include a wireless network provided by a communication provider of the mobile terminal. In one example, the transmission device 106 includes a network adapter (Network Interface Controller, referred to as NIC), which can be connected to other network devices through a base station so as to communicate with the Internet. In one example, the transmission device 106 may be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.
[0066] In this embodiment, a control method for an oxygen-generating air conditioner running on a mobile terminal, a computer terminal or a similar computing device is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.
[0067] Figure 5 1 is a flow chart of a control method of an oxygen-generating air conditioner according to an embodiment of the present application. The oxygen-generating air conditioner comprises a pressure sensor and a first flow valve. The pressure sensor is used to detect the pressure of the output air of the air compressor. The first flow valve is used to control the output flow of the output end of the air compressor. Figure 5 As shown, the method comprises the following steps:
[0068] Step S201, obtaining the current pressure, wherein the current pressure is the current air pressure output by the air compressor;
[0069] Specifically, the pressure sensor monitors the current output air pressure of the air compressor in real time and transmits the data to the controller. The current pressure refers to the actual measured pressure value of the air compressor output air at any given moment. Obtaining the current pressure is the basis for implementing the control algorithm, which provides real-time data for subsequent comparison and adjustment.
[0070] Step S202, obtaining a preset pressure, wherein the preset pressure is a standard air pressure output by the air compressor;
[0071] Specifically, the preset pressure refers to a target value set during design within the optimal pressure range for the molecular sieve to effectively separate oxygen. This value is usually preset based on the optimal working conditions of the molecular sieve and the efficiency requirements of the entire air conditioning system. Obtaining the preset pressure is a standard for comparison with the current pressure to determine whether the air compressor output pressure is within the ideal range.
[0072] Step S203, adjusting the rotation speed of the air compressor and / or adjusting the opening of the first flow valve according to the difference between the current pressure and the preset pressure, until the difference between the current pressure and the preset pressure is less than the preset pressure difference.
[0073] Specifically, by comparing the difference between the current pressure and the preset pressure, the speed of the air compressor and / or the opening of the first flow valve are automatically adjusted to make the current pressure as close to the preset pressure as possible. The preset pressure difference mentioned here is a set allowable deviation. When the difference between the current pressure and the preset pressure is within this allowable deviation, it is considered that the output pressure of the air compressor has reached a stable state and the control process ends.
[0074] If the current pressure is lower than the preset pressure, the speed of the air compressor will be increased to increase the output pressure of the compressed air and make it close to the preset value; if the current pressure is higher than the preset pressure, the speed of the air compressor will be reduced to reduce the output pressure and also make it close to the preset value.
[0075] If it is still difficult to quickly reach the preset pressure by adjusting the air compressor speed, or the design tends to be more precise in pressure control, the air flow entering the molecular sieve can be controlled by adjusting the opening of the first flow valve, thereby indirectly affecting the output pressure of the air compressor. If the pressure needs to be increased, the opening of the first flow valve can be reduced, otherwise it can be increased.
[0076] Through this embodiment, through closed-loop control, the output pressure of the air compressor can be continuously monitored and adjusted to ensure that it is stable within the preset pressure range, and the air compressor speed and flow valve opening are automatically adjusted to avoid unnecessary energy waste, ensure that the air conditioning system operates in the optimal working state, and improve the overall energy efficiency and operating economy. Keeping the air compressor running at a suitable working pressure can reduce excessive load and wear of the equipment, extend the service life of the air compressor, and reduce maintenance costs.
[0077] Specifically, a pressure sensor is installed on the air compressor to monitor the pressure of the output air in real time. When the pressure is lower or higher than the set value, the speed of the air compressor or the opening of the air inlet valve is automatically adjusted to ensure that air with stable pressure is delivered to the molecular sieve.
[0078] Assuming that the oxygen air conditioning system is in operation, the goal is to maintain the air pressure output by the air compressor at 280kPa (preset pressure) to ensure that the molecular sieve separates oxygen and nitrogen in the best condition.
[0079] Get the pressure sensor data of the air compressor output in real time. Assume that at a certain moment, the current pressure measurement value is 270kPa. This pressure value is lower than the preset pressure and needs to be adjusted. The preset pressure is 280kPa, which is the optimal pressure value based on the design and molecular sieve separation efficiency.
[0080] The difference between the current pressure of 270 kPa and the preset pressure of 280 kPa is 10 kPa, which exceeds the allowable range of the preset pressure difference of 5 kPa and needs to be adjusted.
[0081] First, try to increase the output pressure by increasing the speed of the air compressor to approach the preset pressure. For example, assuming that the current air compressor speed is 1800RPM, adjust the speed to 1900RPM to increase the air compression. After the speed adjustment, assuming that the current pressure rises to 275kPa, it is still lower than the preset pressure of 280kPa, but the difference is reduced to 5kPa, which does not reach the target range. At this time, further adjust the opening of the first flow valve.
[0082] The opening adjustment of the first flow valve can further control the air flow entering the molecular sieve. Assume that by reducing the opening of the first flow valve (for example, from 80% to 70%), the air pressure in the air compressor rises further until the current pressure reaches 280kPa, which is equal to the preset pressure, or the difference is reduced to within the allowable range of less than 5kPa. After this, the current state is defined as a stable state, and the speed of the air compressor and the opening of the first flow valve will be maintained at the adjusted values unless subsequent pressure sensor data indicates that further adjustment is required. If the current pressure continues to rise to 285kPa, the output pressure will be reduced by reducing the speed of the air compressor or increasing the opening of the first flow valve to make it close to the target value again.
[0083] In the specific implementation process, the above-mentioned oxygen-generating air conditioner includes a pressure difference sensor, which is used to detect the pressure difference on both sides of the above-mentioned filter. After adjusting the speed of the above-mentioned air compressor and / or adjusting the opening of the above-mentioned first flow valve according to the difference between the above-mentioned current pressure and the above-mentioned preset pressure, the above-mentioned method also includes the following steps: obtaining the current pressure difference, wherein the above-mentioned current pressure difference is the current pressure difference on both sides of the above-mentioned filter; when the above-mentioned current pressure difference is greater than or equal to the preset pressure difference threshold, generating a prompt message, wherein the above-mentioned prompt message indicates that the above-mentioned filter needs to be cleaned and / or replaced.
[0084] In this solution, regular cleaning or replacement of the filter can ensure that it continues to effectively remove impurities from the air and ensure the quality of air received by the molecular sieve, thereby improving the purity of oxygen output and the overall separation efficiency of the air conditioning system. Blockage of the filter may cause a reduction in air flow, affect the normal operation of the air compressor and molecular sieve, and even cause air conditioning failure. By monitoring the pressure difference and cleaning or replacing the filter in time, this situation can be avoided and the stability of the air conditioning system can be improved.
[0085] In the oxygen air conditioning system, the filter is located in the air delivery path between the air compressor and the molecular sieve to remove dust, particulate matter and other impurities in the air, ensuring that the molecular sieve can process clean air and improve its separation efficiency. The differential pressure sensor is installed on both sides of the filter to continuously monitor the pressure difference before and after the filter. The current differential pressure refers to the pressure difference between the two sides of the filter measured by the differential pressure sensor at any given time. As the filter captures more impurities, its resistance will gradually increase, causing the pressure difference to rise. The preset differential pressure threshold is a set standard value used to determine whether the filter needs to be cleaned or replaced. If the current differential pressure exceeds or equals this threshold, it means that the filter is blocked to a level that may affect the performance of the air conditioner. At this time, a prompt message will be generated, which may be displayed on the control panel, sent to the mobile phone application, or through a sound alarm to notify the user that the filter needs to be cleaned or replaced.
[0086] Specifically, a differential pressure sensor is provided for the filter. When the differential pressure on both sides of the filter exceeds the program setting value, it prompts that the filter needs to be cleaned or replaced to ensure smooth passage of air and effective removal of impurities.
[0087] Specifically, assuming that the oxygen air conditioning system is in operation, the cleanliness of the filter needs to be monitored to ensure air quality and efficient operation of the air compressor. The pressure difference on both sides of the filter is continuously monitored, assuming that the current pressure difference measurement value is 100Pa. The pressure difference is caused by the pressure difference before the filter (clean air side) and after the filter (air filtered side), and is an important indicator for judging the cleanliness of the filter.
[0088] The preset pressure difference threshold is a standard value set in the design to determine whether the filter needs to be cleaned or replaced. In this embodiment, it is assumed that the preset pressure difference threshold is 200 Pa. When the actual monitored pressure difference value exceeds or equals this threshold, a maintenance prompt will be triggered.
[0089] Assume that the filter gradually accumulates more dust and impurities, causing the pressure difference to rise to 250 Pa. This value exceeds the preset pressure difference threshold of 200 Pa.
[0090] When the current pressure difference is detected to be greater than or equal to the preset pressure difference threshold, a maintenance reminder message will be generated. The reminder message may be displayed on the control panel as "Filter Cleaning Alert" or a message will be sent to the user through the mobile phone application, saying "High filter pressure difference detected, please consider cleaning or replacing the filter".
[0091] After receiving the prompt message, the user can take immediate action, such as stopping the machine to clean the filter, or deciding whether to replace the filter with a new one based on the usage of the filter.
[0092] In some embodiments, the oxygen-generating air conditioner includes a flow sensor, which is used to detect the output flow of the output end of the air compressor. After adjusting the speed of the air compressor according to the difference between the current pressure and the preset pressure, and / or adjusting the opening of the first flow valve, the method further includes the following steps: obtaining a current flow, wherein the current flow is the current air flow output by the air compressor; obtaining a preset flow, wherein the preset flow is the standard air flow output by the air compressor; adjusting the speed of the air compressor according to the difference between the current flow and the preset flow, and / or adjusting the opening of the first flow valve until the difference between the current flow and the preset flow is less than the preset flow difference.
[0093] In this solution, by precisely controlling the output flow of the air compressor, the molecular sieve can work under the optimal airflow conditions, thereby improving the separation efficiency of oxygen and nitrogen and increasing the purity and amount of oxygen output. Ensuring that the output flow of the air compressor is within the preset range avoids over-compression or under-compression, reduces energy waste, and improves the overall energy efficiency of the air conditioning system.
[0094] Specifically, the flow sensor installed at the output end of the air compressor monitors the current air flow in real time, that is, the actual amount of air output by the air compressor at any time point. Monitoring of air flow is the key to ensuring that the molecular sieve can receive sufficient and stable airflow for oxygen separation.
[0095] The preset flow rate refers to the ideal air flow rate set during design for effective gas separation by the molecular sieve. This value is usually determined based on the performance parameters of the molecular sieve and the overall needs of the oxygen production and air conditioning system to ensure the efficiency and quality of oxygen production.
[0096] When the monitored current flow rate is lower than the preset flow rate, the air output will be increased by increasing the speed of the air compressor or reducing the opening of the first flow valve to achieve the preset flow rate. Conversely, if the current flow rate is higher than the preset flow rate, the air compressor speed will be reduced or the opening of the first flow valve will be increased to reduce the air output.
[0097] The preset flow difference is an allowable deviation range. When the difference between the current flow and the preset flow drops within this allowable range, it is considered that the flow regulation has been completed and a stable state has been reached.
[0098] Specifically, a flow sensor may be installed to optimize the operating parameters of the air compressor based on air flow feedback to ensure stable air delivery to the molecular sieve.
[0099] Specifically, assume that the design of the oxygen-generating air conditioning system requires the preset flow rate of the air compressor to be 1200L / min during normal operation to achieve the best oxygen production efficiency. A flow sensor is installed inside the air conditioner to monitor the current flow rate in real time, and a control module is used to adjust the air compressor speed and the opening of the first flow valve.
[0100] When the air conditioner is started, the flow sensor starts working and continuously monitors the current flow rate output by the air compressor. Assume that when the air conditioner is just started, the current flow rate is displayed as 1000L / min because the air compressor has not yet reached full speed.
[0101] The preset flow rate of 1200 L / min is obtained, and this value is compared with the current flow rate of 1000 L / min monitored by the flow sensor, and it is determined that the difference between the two is 200 L / min.
[0102] Based on the difference between the current flow rate and the preset flow rate, it is decided to take adjustment measures. First, try to increase the speed of the air compressor to increase the output flow rate. Assuming that the current air compressor speed is 1500RPM, adjust it to 1700RPM. After the adjustment, the flow sensor detects that the air flow rate output by the air compressor has risen to 1100L / min.
[0103] Although the current flow rate has increased to 1100L / min by adjusting the air compressor speed, there is still a difference of 100L / min from the preset flow rate of 1200L / min. In order to further increase the flow rate to the preset standard, the opening of the first flow valve is adjusted. The opening of the first flow valve is currently 50%, which is increased to 60%. After this adjustment, the current flow rate rises to 1180L / min.
[0104] Compare the current flow rate 1180L / min with the preset flow rate 1200L / min again, and the difference is 20L / min this time. Assuming the preset flow difference is 30L / min, it means that the difference between the current flow rate and the preset flow rate is less than the maximum allowable deviation. It is considered that the flow rate has reached a stable state and no further adjustment is required.
[0105] After reaching a stable state, continue to monitor the data of the flow sensor. If the current flow monitored in the future is lower than the preset flow, and the difference exceeds the preset flow difference again (for example, it drops to 1150L / min, the difference is 40L / min), the above process will be repeated to adjust the air compressor speed or the opening of the first flow valve until a stable state is reached again.
[0106] In a specific implementation process, the oxygen-generating air conditioner includes an oxygen concentration sensor, which is used to detect the oxygen concentration at the output end of the molecular sieve. After adjusting the rotation speed of the air compressor and / or adjusting the opening of the first flow valve according to the difference between the current pressure and the preset pressure, the method further includes the following steps: obtaining a current oxygen concentration, wherein the current oxygen concentration is the current oxygen concentration output by the molecular sieve; obtaining a preset oxygen concentration, wherein the preset oxygen concentration is the standard oxygen concentration output by the molecular sieve; adjusting the working temperature of the molecular sieve and / or adjusting the working pressure of the molecular sieve according to the difference between the current oxygen concentration and the preset oxygen concentration, until the difference between the current oxygen concentration and the preset oxygen concentration is less than the first preset oxygen concentration difference.
[0107] In this solution, by precisely controlling the working conditions of the molecular sieve, it is possible to continuously produce oxygen concentration that meets the preset standards, ensure the stability of oxygen quality, and meet the health needs of users. Dynamically adjusting the working conditions of the molecular sieve avoids unnecessary energy consumption, improves the energy efficiency of the entire air conditioning system, and reduces operating costs.
[0108] Specifically, the oxygen concentration in the molecular sieve output gas is monitored in real time by an oxygen concentration sensor. The current oxygen concentration reflects the oxygen output of the air conditioner at any point in time.
[0109] The preset oxygen concentration is the target set during design, that is, the oxygen concentration level that the molecular sieve is expected to produce, in order to meet specific oxygen quality standards and user needs.
[0110] The difference between the current oxygen concentration and the preset oxygen concentration determines whether and how to adjust the working conditions of the molecular sieve. If the current oxygen concentration is lower than the preset oxygen concentration, the molecular sieve's operating temperature or pressure may be increased to improve the oxygen separation efficiency; conversely, if the current oxygen concentration is too high, the molecular sieve's operating temperature or pressure may be reduced to avoid wasting gas sources or affecting the oxygen volume quality.
[0111] An allowable oxygen concentration deviation range is set. When the difference between the current oxygen concentration and the preset oxygen concentration is lower than the set threshold, it is considered that the oxygen concentration has stabilized within the target range and no further adjustment is made.
[0112] Specifically, a flow control valve and an oxygen concentration sensor are installed at the outlet of the molecular sieve to monitor the separation effect of oxygen and nitrogen in real time. If the separation efficiency decreases, the separation process can be optimized by adjusting the operating temperature, pressure and other parameters of the molecular sieve.
[0113] Assume that the design requirement is that the preset concentration of the molecular sieve output oxygen is 23% to meet the healthy demand for oxygen concentration in the indoor environment. An oxygen concentration sensor has been installed in the air conditioner to monitor the current oxygen concentration in real time, as well as a molecular sieve module with temperature and pressure regulation functions.
[0114] After the air conditioner is started, the oxygen concentration sensor begins to continuously monitor the oxygen concentration produced by the molecular sieve. Assume that at the beginning of the air conditioner operation, the current oxygen concentration is 20%.
[0115] The controller obtains the preset oxygen concentration of 23% from the system configuration and compares it with the current oxygen concentration of 20%, determining that the difference between the two is 3%.
[0116] Since the current oxygen concentration is lower than the preset concentration, the controller determines that the concentration of oxygen output needs to be increased. According to the system design, the oxygen separation efficiency can be affected by adjusting the working temperature and / or working pressure of the molecular sieve.
[0117] The first step is to try to adjust the working temperature of the molecular sieve. Assume that the current working temperature of the molecular sieve is 20°C, and the controller increases the working temperature to 25°C. The working temperature of the molecular sieve has a direct impact on the oxygen-nitrogen separation efficiency. Generally, appropriately increasing the temperature helps improve the separation efficiency.
[0118] If the current oxygen concentration still does not reach the preset concentration after adjusting the temperature, the controller will try to change the working pressure of the molecular sieve. Assuming that the current working pressure of the molecular sieve is 4 bar, the controller will increase it to 5 bar. Increasing the working pressure can further promote the separation of oxygen and nitrogen and increase the oxygen concentration.
[0119] After a series of adjustments, assume that the current oxygen concentration rises to 22%. The controller again compares the current oxygen concentration with the preset oxygen concentration, and the difference is 1%. If this difference is less than the first preset oxygen concentration difference (for example, set to ±2%), it is considered that the oxygen concentration has stabilized within the target range and no further adjustments are made. If the difference still exceeds the allowable range, the controller will continue to repeat the above process until the difference between the current oxygen concentration and the preset oxygen concentration is within the allowable range.
[0120] After reaching a stable state, the data of the oxygen concentration sensor is continuously monitored. Once it is detected that the current oxygen concentration deviates from the preset concentration, the adjustment mechanism is immediately activated to maintain the continuous stability of the oxygen concentration.
[0121] In some embodiments, the oxygen-generating air conditioner includes a second flow valve, which is used to control the output flow of the output end of the molecular sieve. After adjusting the speed of the air compressor according to the difference between the current pressure and the preset pressure, and / or adjusting the opening of the first flow valve, the method further includes the following steps: obtaining the oxygen demand, wherein the oxygen demand is the required oxygen concentration corresponding to the indoor area; adjusting the opening of the second flow valve according to the difference between the current oxygen concentration and the oxygen demand, until the difference between the current oxygen concentration and the oxygen demand is less than the second preset oxygen concentration difference.
[0122] In this solution, through real-time monitoring and dynamic adjustment, the indoor oxygen concentration can be accurately controlled to ensure that it is always at the most beneficial level for human health, providing an indoor environment conducive to life. The oxygen supply is dynamically adjusted according to actual needs to avoid excessive or insufficient oxygen production, thereby improving energy utilization efficiency, reducing unnecessary energy waste, and reducing operating costs. Ensuring that the indoor oxygen concentration is stable at an appropriate level provides users with a comfortable and healthy living or working environment, improving the quality of life of users.
[0123] Specifically, the required oxygen concentration for the indoor space is calculated based on the indoor area and the preset health and comfort standards. For example, for a 30-square-meter room, the required oxygen concentration will be set based on human health and activity needs. The oxygen concentration sensor monitors the current indoor oxygen concentration in real time to reflect the actual oxygen supply status.
[0124] Based on the difference between the current oxygen concentration and the oxygen demand, the opening of the second flow valve is dynamically adjusted, which directly affects the amount of oxygen delivered to the room after the molecular sieve separates the oxygen. If the current oxygen concentration is lower than the oxygen demand, the opening of the second flow valve will be increased to increase the oxygen supply; conversely, if the current oxygen concentration is too high, the opening of the second flow valve will be reduced to reduce the oxygen supply.
[0125] An allowable oxygen concentration deviation range is set. When the difference between the current oxygen concentration and the oxygen demand is lower than the set threshold, it is considered that the oxygen concentration has stabilized within the target range and the second flow valve opening is no longer adjusted.
[0126] Specifically, the oxygen flow rate is automatically adjusted according to the air supply demand of the indoor unit and the indoor oxygen concentration to ensure that the indoor air always maintains an appropriate oxygen content and fresh air supply.
[0127] Assume that the design requires the calculation of oxygen demand based on the indoor area to maintain the indoor oxygen concentration at around 21%, which is set based on the general standard of human health and comfort. Taking an 80-square-meter living room as an example, it is calculated that in order to meet the oxygen demand of the space, the current oxygen concentration should be maintained at 21%.
[0128] According to the area of the living room (80 square meters), combined with the preset health and comfort standards, the required oxygen concentration in the space is calculated to be 21%. This demand is based on a comprehensive assessment of multiple factors such as indoor human activity, respiratory rate, and space volume.
[0129] The oxygen concentration sensor installed in the air conditioner continuously monitors the current oxygen concentration in the room. In the early stage of air conditioning operation, the current oxygen concentration may be 20%.
[0130] The controller obtains the difference between the current oxygen concentration of 20% and the oxygen demand of 21%, that is, 1%. If the current oxygen concentration is lower than the demand, the controller will increase the opening of the second flow valve to increase the oxygen supply and improve the indoor oxygen concentration. Assuming that the initial second flow valve opening is 50%, the controller adjusts it to 60%. After adjustment, the current oxygen concentration is continuously monitored, assuming that the concentration rises to 20.5%.
[0131] The controller again calculates the difference between the current oxygen concentration of 20.5% and the oxygen demand of 21%, which is 0.5%. If this difference is still greater than the second preset oxygen concentration difference (for example, set to ±0.3%), the controller will continue to adjust the opening of the second flow valve until the difference between the current oxygen concentration and the oxygen demand is within the allowable deviation range. Assume that after further adjustment, the current oxygen concentration is stabilized at 20.8%.
[0132] When the difference between the current oxygen concentration and the oxygen demand is lower than the second preset oxygen concentration difference, the oxygen concentration is considered to be stable within the target range, and the opening adjustment of the second flow valve will be temporarily stopped. However, the data of the oxygen concentration sensor will be continuously monitored, and once the concentration is detected to deviate from the target range, the adjustment mechanism will be immediately activated to maintain the stability of the indoor oxygen concentration.
[0133] In addition, a central control system (i.e., a controller, the executive body of the above solution of this application) can also be set up to integrate the data of all sensors, and uniformly monitor and adjust the operating parameters of the entire system to ensure stable operation of the system and give full play to the advantages of simplified structure and reduced costs. At the same time, the operating time and fault records of the equipment are managed through the control system to facilitate maintenance and optimization.
[0134] In addition, the compressor of the present application can also complete the entire automatic cleaning process at a normal working frequency.
[0135] The embodiment of the present application also provides a control device for an oxygen-generating air conditioner. It should be noted that the control device for the oxygen-generating air conditioner in the embodiment of the present application can be used to execute the control method for the oxygen-generating air conditioner provided in the embodiment of the present application. The device is used to implement the above-mentioned embodiments and preferred implementation modes, and the descriptions that have been made will not be repeated. As used below, the term "module" can implement a combination of software and / or hardware for a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, the implementation of hardware, or a combination of software and hardware, is also possible and conceivable.
[0136] The following is an introduction to the control device of the oxygen-generating air conditioner provided in the embodiment of the present application.
[0137] Figure 6 1 is a structural block diagram of a control device for an oxygen-generating air conditioner according to an embodiment of the present application. Figure 6 As shown, the device comprises:
[0138] A first acquisition unit 100 is used to acquire a current pressure, wherein the current pressure is the current air pressure output by the air compressor;
[0139] A second acquisition unit 200 is used to acquire a preset pressure, wherein the preset pressure is a standard air pressure output by the air compressor;
[0140] The first control unit 300 is used to adjust the speed of the air compressor and / or the opening of the first flow valve according to the difference between the current pressure and the preset pressure until the difference between the current pressure and the preset pressure is less than the preset pressure difference.
[0141] Through this embodiment, through closed-loop control, the output pressure of the air compressor can be continuously monitored and adjusted to ensure that it is stable within the preset pressure range, and the air compressor speed and flow valve opening are automatically adjusted to avoid unnecessary energy waste, ensure that the air conditioning system operates in the optimal working state, and improve the overall energy efficiency and operating economy. Keeping the air compressor running at a suitable working pressure can reduce excessive load and wear of the equipment, extend the service life of the air compressor, and reduce maintenance costs.
[0142] During the specific implementation process, the oxygen-generating air conditioner includes a pressure difference sensor, which is used to detect the pressure difference on both sides of the filter. The device also includes a third acquisition unit and a generation unit. The third acquisition unit is used to obtain the current pressure difference after adjusting the speed of the air compressor and / or adjusting the opening of the first flow valve according to the difference between the current pressure and the preset pressure, wherein the current pressure difference is the current pressure difference on both sides of the filter; the generation unit is used to generate a prompt message when the current pressure difference is greater than or equal to the preset pressure difference threshold, wherein the prompt message indicates that the filter needs to be cleaned and / or replaced.
[0143] In this solution, regular cleaning or replacement of the filter can ensure that it continues to effectively remove impurities from the air and ensure the quality of air received by the molecular sieve, thereby improving the purity of oxygen output and the overall separation efficiency of the air conditioning system. Blockage of the filter may cause a reduction in air flow, affect the normal operation of the air compressor and molecular sieve, and even cause air conditioning failure. By monitoring the pressure difference and cleaning or replacing the filter in time, this situation can be avoided and the stability of the air conditioning system can be improved.
[0144] In some embodiments, the oxygen-generating air conditioner includes a flow sensor, which is used to detect the output flow of the output end of the air compressor. The device also includes a fourth acquisition unit, a fifth acquisition unit and a second control unit.

[0145] In this solution, by precisely controlling the output flow of the air compressor, the molecular sieve can work under the optimal airflow conditions, thereby improving the separation efficiency of oxygen and nitrogen and increasing the purity and amount of oxygen output. Ensuring that the output flow of the air compressor is within the preset range avoids over-compression or under-compression, reduces energy waste, and improves the overall energy efficiency of the air conditioning system.
[0146] In a specific implementation process, the oxygen-generating air conditioner includes an oxygen concentration sensor, which is used to detect the oxygen concentration at the output end of the molecular sieve. The device also includes a sixth acquisition unit, a seventh acquisition unit and a third control unit. The sixth acquisition unit is used to obtain the current oxygen concentration after adjusting the rotation speed of the air compressor and / or adjusting the opening of the first flow valve according to the difference between the current pressure and the preset pressure, wherein the current oxygen concentration is the current oxygen concentration output by the molecular sieve; the seventh acquisition unit is used to obtain the preset oxygen concentration, wherein the preset oxygen concentration is the standard oxygen concentration output by the molecular sieve; the third control unit is used to adjust the working temperature of the molecular sieve and / or the working pressure of the molecular sieve according to the difference between the current oxygen concentration and the preset oxygen concentration, until the difference between the current oxygen concentration and the preset oxygen concentration is less than the first preset oxygen concentration difference.
[0147] In this solution, by precisely controlling the working conditions of the molecular sieve, it is possible to continuously produce oxygen concentration that meets the preset standards, ensure the stability of oxygen quality, and meet the health needs of users. Dynamically adjusting the working conditions of the molecular sieve avoids unnecessary energy consumption, improves the energy efficiency of the entire air conditioning system, and reduces operating costs.
[0148] In some embodiments, the oxygen-generating air conditioner includes a second flow valve, which is used to control the output flow of the output end of the molecular sieve. The device also includes an eighth acquisition unit and a fourth control unit. The eighth acquisition unit is used to obtain the oxygen demand after adjusting the speed of the air compressor and / or adjusting the opening of the first flow valve according to the difference between the current pressure and the preset pressure, wherein the oxygen demand is the required oxygen concentration corresponding to the indoor area; the fourth control unit is used to adjust the opening of the second flow valve according to the difference between the current oxygen concentration and the oxygen demand until the difference between the current oxygen concentration and the oxygen demand is less than the second preset oxygen concentration difference.
[0149] In this solution, through real-time monitoring and dynamic adjustment, the indoor oxygen concentration can be accurately controlled to ensure that it is always at the most beneficial level for human health, providing an indoor environment conducive to life. The oxygen supply is dynamically adjusted according to actual needs to avoid excessive or insufficient oxygen production, thereby improving energy utilization efficiency, reducing unnecessary energy waste, and reducing operating costs. Ensuring that the indoor oxygen concentration is stable at an appropriate level provides users with a comfortable and healthy living or working environment, improving the quality of life of users.
[0150] The control device of the oxygen-generating air conditioner includes a processor and a memory. The first acquisition unit, the second acquisition unit and the first control unit are stored in the memory as program units, and the processor executes the program units stored in the memory to implement corresponding functions.
